Nov. 16 1926.



Application filed November 20, 1925. Serial No. 70,247.

The object of my invention is to provide a sleeve of this class which will make unnecessary the use of a junction box where wires are passed 1n a bulldmg 1n the conventional manner.

For a more detailed description of my invention, reference is to be had to the accompanying drawings, forming apart hereof, in which- *Y Figure 1 is a longitudinal view of a conduit with wires and my improved sleeve.

Figure 2 is a sectional View of the same. 'i'

Figure 3 is a perspective view of a cable or wire holder.

Throughout the various views of the drawings, similar reference characters designate similar parts.

1 indicates a building in which are mounted the usual tubes 2, which arefixed in the building in any suitable manner. These tubes receive Wires or cables" 3 which are drawn through in the conventional way. The end of each tube, which is exposed, is screw threaded at 4 and provided with a suitable sleeve 5 which rests over the end of the tube and has@ conical bore which receives a perforated plug 6 and forces the samel into intimate contact with the wires so that the wires are securely held. This plug, in the preferred embodiment' of my invention, is formed of three parts 7, which, when taken together, have an exterior surface which is thevfrustrum of a cone so it will fit snug in the sleeve 5, as indicated, and they also have three bores '8 .for the cables 3.

Each sleeve 5 has a rounded end 9 which engages a sleeve 10 with rojections 11 mounted thereon by-means oFwhich it may be turned. This sleeve is screw threadedat 12 to engage correspondingthreads on the removable junction sleeve 13.'

In view ofthe foregoing. the usepof my improved removable junction sleeve will bev readily understood. Assuming the wires and conduits to be in place, as'above de-l scribed, and the sleeves 5 mounted thereon and the plug 6 in place with its component parts gripping the wires, as above set forth,

the wires or cables are then passed'through rthe sleeve 1.3 which is released from one tional manner, the sleeve 13 is then raised to its proper position so as to cover the wires and their connecting tapes and then the other sleeve 10 lis turned true so as to hold the removable junction sleeve 13 `in place. When it is desired to get at the connections between the ends of the wires 3, one of the sleeves 10 can be unscrewed and then the removable junction sleeve 13 can be slid, as above described, and access can be had to the joints.

While I have shown and vdescribed one elnbodiment of my invention, it` is obvious that itis not restricted thereto, but that it is broad enough to cover all structures that I come within the scope of the annexed claims. Having` thus described my invention, what I claim is: i

1. Two conduits, a sleeve threaded on the end of each conduit a substantial distance and having at one end an internal shoulder adaptedto cooperate with the end of each conduit and at the other end being rounded, a junctionsleeve .extending between the two conduits and asubstantial distance over said sleeves, a secondvsleeve threaded upon each end of sald junction sleeve and havmg an internal shoulder engaging said roundedv end upon said first mentioned sleeves.

2. Two, conduits with screw threads at( their adjacent ends, a sleeve, threaded on learch .of such ends extending a substantial distance, a' junction s leeveuextending between the two conduits and a substantial dis,V
